Application mea october c, 192s. serial No. 666,928.

The present invention relates to an improvementXin washing machines, andmore particularly toI an' improvementin power operated wringers for use in connection with a compartmented' laundry trays such for example as shown in our pending application Serialr No. 540,733, filed Mar. 3, 1922, of which this application' is in part a continuation. Une oit-our objects is to provide a l@ wringer operated by power andadapted t'o be readily controlled to safeguard the operator 4and all working operations, and another object involves the mounting of a clothes wringer in a movable or slidable position upon the tub or tray and in operable connection with aymotor, whereby washing of the goods may take place in one compartment and rinsing and wringing operations 'may be successively carried on step by step with facility and despatch by shifting the wringer 'to other compartments ofthe tub or tray. t ,v

Fig. 13 is a cross section on line 13- -13 of Fig; 10 showing the telescopic shaft and. telescopic .hous'mg` 65 The invention comprises an elongatedV receptacle, tub or wash tray 2, which is molded oi concrete and' made with two transverse division walls 3 and 4 to provide three separate washingfcompartinents 5, 6 and 7, respectively. The rear wall 8 is commonzto 0G all these compartments and rises to the same elevation as the division walls and supports separate hot and cold water' faucets 9. l Drain outlets 10 are also Vprovided which are connected up in any suitable way to a single discharge pipe, and a washing and agitating device is incorporated in one of the compartments, which device may be of any suitable kind but as exemplified in the drawings consists Otan air distributingand agitat- 7G ing devicecomprising a series of radiating pipes 11 embedded within the concrete hottom 12 of compartment 5. These pipes ter g minate in vertical nipples 13 having relatively small outlets, and the several pipes 11` 75. branch from acommon air intake connection l5 which extends rearwardly from the tray or tub wherea -U-shaped pipe 19 is de tachably secured thereto.

An air pump 21 located beneath the tray 80 has a pipe connection with the bottom end of U-member 19 which extends upwardly outside of the rear w-all above the normal level of the body, of water therein so that the water is trapped and cannot flow back 'through these pipes to the pump, whichf pump may be of the rotary type or any other 1nd capable of producing ,and delivering' a continuous flow of air of six to eight vcubic feet per minute through the relatively 9u small ipes 15 and 19. Pump 21 is driven by a s iftable belt 23 from a pulley P on the armature shaft` of an electric motor M, and a belt shifting device 23 is provided,

.which is controlled by. a hand lever V24g o5 pivotall mounted upon a bracket aflixed to Vthe sk eton supporting frame F Vfor the washtray. l v Motor Mis lalso arranged to operate aA wringer 26 which is supported to slidev or 100 roll upon the parallel upper edges of 'the 'rear and front .walls of the wash tray, the

operating connectionsbetweenV themotor and the wringer being located at the rear Y side of the tray. Thus, a friction clutch 27 '101 is adapted' to connect and disconnect 'the motorgshaftfromA a; separate motor shaft extension 27 having. a worin pinion 28v meshing: with a worm gear 29 ,u n the lower endof a telescopic extensib e shaft ,lll-

mounted upon a slidable or movable base 30. The -upper and lower` sections of shaft l are` journaled in separate swiveled brackets 31 and 32, respectively, and a bevel ge ar 33 for the uppershaft section meshes with a similar gear 34 at the rear end of a jointed horizontal shaft 35 carrying'v the upper ,rubber roller 36 lof the wringer. S aft 35 is partly journaled yin and' suported by a vertical bracket 37 and partl y upright standards -40 and 41 rigidly 2o ,operations the wringer is usually stationed directly above one or the other of the two division walls of the tray where the transfer of goods may be readily effected from one compartment. tothe other, and it is also readily shifted lengthwise across the compartments to either end .of thetray. The upright standards 40-*41 are joined together by an inclined delivery board .39.

Aand have curved overhangingends within which shaft 35 hasl rotatable bearing. The

-end portions 42-of the wringer base are extended for stability and have rollers adapted to ride -upon the `longitudinal edges of the tray, and a thumb or hand screw 38 serves to lock the wringer against movement upon the tray.

`The lower rubber roller of the wringer is mounted upon a shaft 51 which is free .standards 40 and 41.

the up pivotedilocking member 57 int 'lbail or handle having to rotate and also to slide vertically within limits inslotted supporting arms 52 which are pivotally attached or h1nged at 53 upon These arms are rigidly united at their front ends by a feed board 49, and each has a hollowbox or dependent portion 54 within -which a coiled compression spring 55 confined and adapted to exert an upward pressure 'on a slidable bearing block for the Vroller shaft 51.` A tightening or tension Vscrew 5 6 bears againstthe bottomend of each springV and extends through the lower end of each box 54 where it can be reached and turned when occasion requires.` However, arms 52 and lower roller.50 are free to drop away from rl roller 36 unless sup rted by a lilgform of a l hooks or catches 58 adapted to interlock -with rejections 59 on arms 52, see Fig. 6, -This handle or bail 57 has-side arms loosel sleeved uponupper shaft 35 at each end' ofthe wrmger, andv the lower roller can be caused to drop away from the upper roller by gravity' by pres- -ing thelgpleee rearwardly either by the hand, 'forearm, elbow or evenzthe head. In

this way instant release-maybe effected of the goods and the strain on the wringer re- 'A further importantsafe-guard is pro. y vided, however, to avoid accident and injur to the machine and operator. Thus, this wringer is particularly designed to operate only when clutch 27 is in driving connection withmotor M, a condition which can only be maintained by the operator alone. That is to say, when the operator is using the Wringer it is necessary for the operator to depress a pivoted pedal (iO-extending length- Wise of the tray. The wringer is 1n action only when this pedal is down, the pedal being connected with the clutch and also provided with -a` spring 61 which 'shifts tho pedal normally to throw out the clutch the moment the operator relieves the foot ressure-u on thepedal. Consequently, if either or -botli hands are caught or' endangered the operator can cut oil the; power and stop the wringer instantly. by merely relieving the foot pressure on the treadle.

In. a Washing joperation the goods are placedl in the` first com artment 5 which has been filled to a suitab evheight Wit-h water containing soap -or Vany other cleansing agent, and a cover 62 either conical or flat, isplaced over the compartment but spaced apart from the goods within the water. The electric motor having been'switched on, it is only necessary thento shift the belt by lever 21, Whereuv on a continuous stream ofv air is pum e into the bottom of a compartment 5 w ere it is compelled to pass upward through the water wherever liberated at the perforation 13. Onl a fewL such perforations are used and t ese are spaced widel apart, one at the middle and one near eaci corner of the compartment. As a result the water and goods `are constantly agitated;

the presence'of the goods prevents the air from escaping on straight vertical lines through the waterg-the istribution of the move and shift the oods from place to place and to rub the fol with frictional cleansing effect; foam and suds gather on the surface beneath the cover and y the turbulent .water disseminates it through the goods which rise and appear or the surface; and a thorough and complete cleansing of the goods is obtained in a very short time. During v,this -operation the mayl division wa 3, so that at the en of the operation the goods may, if desired, be passed through the wringer-to the middle r, ent.' 'When the' goods have been into second compartment 6 by goods and drawn toward be clamped to the-tra` aboveair and the changing lines of force tend toV ofthe goods together l the wringer and rinsed or otherwisetreated in middle compartment 6, the Wringer is shifted to the opposite end above division wall 4 where the wet goods may be again passed through the wringer into compartment 7 preliminary to final wringing and drying operation. This last mentioned operation is performed aftervthe wringer has lheen shifted to the extreme end of the tray where it may be fixed in an overhanging discharge position above a wash basket. Wash ing and rinsing operationsl in the separate compartments and the wringing of goods may proceed simultaneously. That isto say, whilea batch of goods is being washed in the tirst compartment, another batch of goods may be undergoing a rinsing operation in 'the second compartment, While the operator.

is passing rinsed goods through the wringer into the third compartment. A foldable extension F is also provided at one end of the skeleton frame to seat a wash basket or other receptacle for the goods underneath the wringer when shifted to that end of the tra v In shifting the wringer the extensible shaft 30`at` the rear of the. tray telescopes and swings to different angles without disconnecting the wringer from the source of power, although when the operator releases the foot pressure on the treadle and the treadle spring throws out clutch 27, the

,wringer is broughttoan instant stop by means of brake mechanism comprising .a

^ disk 65' on extension shaft 27', a braking member 66 opposite said disk, and an o erating arm 64 on the rock shaft 63 w ich j wash tray vcompartmented receptacle, a wringer movable lengthwise of said receptacle, a motor operatively connected with said wringer, and controlling means for said motor and wrinver comprising a treadle having a 'pedall extending lengthwise at the front side of :said receptacle, wherebythe operator standing in front of any compartment may start and stop the wringer even though the latter may be situated adjacent another distantly located compartment.
